Green roof MobiRoof: How to install the elements and maintain them sustainably
The ready-to-use MobiRoof green roof system consists of a plant cassette filled with substrate and six to eight different sedum species. The cassettes are simply placed together, creating a green roof in no time.
Technical information
The external dimensions of the cassettes are 50 x 50 x 6 cm (=0.25 m²). Four cassettes are required for 1 m² of green roof. The cassette is filled with a substrate that, in addition to serving as a nutrient medium, also provides drainage and water storage. The water storage capacity is approximately 20 liters per m². This capacity can be increased by applying a drainage layer beneath the cassette.
Recommendations for use
The MobiRoof system can be used on both flat roofs and roofs with a slight slope (up to approximately 20% or 10°). MobiRoof can be installed without any additional equipment. It can be used on roofs with a greater slope, but in this case, a securing system, such as an L-profile, is recommended.
If the roof covering does not provide root protection, a root barrier made of water-permeable foil should first be installed.
The cassettes can be divided at intervals of 25 cm across the webs, for which a saw can be used.
Gravel should be placed on the outside of the roof, around skylights and drains, to positively influence the microclimate and to avoid adverse wind effects under the cassettes.

How to keep your green roof fit
MobiRoof requires very little maintenance. Annual pruning and fertilizing is sufficient. Irrigation is generally not necessary in German climates. However, during periods of extreme drought (>4 weeks), irrigation is necessary.
Care
Maintenance should take place once or twice a year:
General control
Fertilize with sedum fertilizer in spring
Cut dead plants, often from mid-September onwards, whereby the green cuttings of the finer plants can be left on the roof and the cuttings of the coarser ones should be removed.
